In 2371, returning from consultations at a Bajorancolony, MajorKira Nerys and Odo detected a Maquis attack in progress. They pursued the attacking ship in the Mekong but due to prevailing conditions, the pursuit takes them down to the surface of a moon with an atmosphere that was impenetrable to the Runabouts sensors.

The Star Trek Encyclopedia (2nd ed., pp. 296, 473) listed two registries for this runabout: NCC-72617 in the main entry and NCC-72917 in the starship chart. The registry was seen briefly, yet not clearly, in "Whispers".

The Encyclopedia noted that the ship was named after the eponymous river in southeast Asia.
